How an address is written in Laos

This is the order Laos's postal service expects. Square brackets mark what you replace.

[Recipient name]
[Street address]
[Postal code (01160)] [City]
LAOS

A postal code is optional in Laos addresses — mail is deliverable without one, though including it speeds up sorting.
